Question

7. For each equation, replace the ? with the correct isotopic or particle symbol, 1 number and atomic number/number of protons. (10 points) including mass 89 b. en c. 239 204 13 d. e. Circle the reaction that is an example of nuclear fusion f. Draw a rectangle around the reaction that is an example of nuclear fission. 8. Use the following information to calculate the energy released in KJ/mole from this reaction( 0 points) Atomic Mass of Mg-28 = 27.983 88 amu Atomic Mass of Al-28 -27.98191 amu Mass of a Beta particle 0.00055 amu

Explanation / Answer

Ans 7 is correct

Ans 8

Mass before reaction = 27.98388 amu

Mass after reaction = 0.00055 + 27.98191 = 27.98246 amu

Mass defect = 27.98388 - 27.98246

= 0.00142 amu x 1.66 x 10^-27 kg/amu

m = 2.3572 x 10^-30 kg

E = m x c2

= 2.3572 x 10^-30 kg x (299792458 m/s)^2

= 2.118 x 10^-13 J/mol

= 2.118 x 10^-16 kJ/mol
